abstract this study investigated the predictability of variables from a motivational framework as well as individuals qualities to predict three non-linguistic outcomes of language learning. gardners socio-educational model with its measures has been used in the current study. individual qualities presented in this study include (1) age, (2) gender, and (3) language learning experience. the...
Electrification to rural and remote areas with limited or no access to grid connection is one of the most challenging issues in developing countries like Iran. Most of electricity demand is met by diesel generators in Iran remote areas, although they create environmental problems and economic concern. These issues can be minimized by hybrid renewable energy systems. This research paper aims at...
Individual blade pitch state space (IBP SS) control and disturbance accommodating control (DAC) that reject wind speed perturbations are applied on a 5 MW wind turbine mounted on the barge and tension leg floating platforms for performance comparison in above rated wind speed region. The DAC used in this study is simply an IBP SS controller with a wind speed disturbance rejection component. For...
In recent years, there has been a fast growth in wind energy conversion system (WECS). There are two general types of wind turbines in WECS: fixed speed wind turbines and varying speed wind turbines.Permanent magnet synchronous generator (PMSG) is one of the most attractive generators for the varying speed turbine WECS.In this paper, a fuzzy controller is proposed to control the current source ...
this exploratory study aimed to investigate a possible relationship between learners’ beliefs about language learning and one of their personality traits; that is,locus of control (loc). both variables, beliefs and locus of control, are assumed to influence the language learning process. the internal control index (ici) and the beliefs about language learning inventory (balli) were administered...
It’s important to realize, optimized dispatching of generating units would be useless without a method of control. Frequency regulation in interconnected network is one of the main challenges posed by wind turbine in modern power system. Obviously the method of load frequency control (LFC) plays a vital role in large interconnected power system. However the modern LFC should be able to handle c...
• How large of an effect can the temporal variation of wind power have on the value of wind in different wind resource areas? • Which locations are affected most positively or negatively by the seasonal and diurnal timing of wind speeds? • How compatible are wind resources in the Pacific Northwest and California with wholesale power prices and loads in either region? • Can modeled/estimated win...
the current thesis is composed in five chapters in the following fashion: chapter two encompasses the applied framework of the project in details; the methodology of carl gustav jung to explain the process of individuation, the major archetypes and their attributes and his techniques to assess the mind’s strata are all explained. moreover, the austrian psychoanalysts, heinz kohut’s models of a...
Two important and upcoming technologies, microgrids and electricity generation from wind resources, are increasingly being combined. Various control strategies can be implemented, and droop control provides a simple option without requiring communication between microgrid components. Eliminating the single source of potential failure around the communication system is especially important in re...
